Digital terrestrial TV services such as Freeview come to your TV set via an aerial. Ideally this should be mounted outside and as high as possible. You may also get good reception if it is inside, for example in the loft, but a set-top aerial may not be satisfactory.
To get the best reception you need to make sure that your aerial is in good condition and is pointing towards the best local transmitter. An outdoor aerial can deteriorate or be knocked or blown out of its correct position, and cables and connections from the aerial to the TV set can become corroded. Older aerials, cables and connections may need replacing, especially if you live near the sea where corrosion can happen quickly.
Picture break-up, clicking sounds or no picture at all may mean that the signal reaching your set-top box or digital TV is too weak.
If you have had this problem for a long time, you may need to upgrade or replace your aerial.
If the problem has just started, check today's transmitter work to see if your local transmitter is affected, and try resetting your set-top box or digital TV. If possible, check another TV set connected to a different aerial - for instance, at a neighbour's - to see if that has the same problem.
If only your set is affected:
Unlike analogue TV, you cannot get ghosting with digital TV.
We suggest that work on your aerial is carried out by a professional aerial installer, either one registered with the CAI (Confederation of Aerial Industries) or a Registered Digital Installer. If you are having a new aerial installed in order to receive digital TV, a CAI benchmarked aerial will give the best results.
If you share a communal aerial (for example, in a block of flats) and you are having reception problems, the aerial may be faulty. See if other residents using the same aerial have the same problem.
If you want to go digital, you may find that the communal aerial is not suitable and needs upgrading.
For queries about a communal aerial, you need to contact whoever is responsible for the building - the management company, council or landlord. There is information about digital switchover for landlords and property managers on the Digital UK website.
